So what:Last quarter, investors sold when revenue came in well short of Wall Street's target. This time, DG's $0.15 per share loss came up well short of the $0.05 a share profit analysts were expecting. Wall Street's target also appears to have accounted for the summer's purchases of MediaMind and EyeWonder, the costs of which cut into earnings.

Now what: I'd love to tell you that sell-off makes DG cheap, but today's action puts the stock right back where it was three months ago: trading for half analysts' long-term earnings growth projections. If only we could trust their guesses. After consecutive misses, I don't see the logic in doing so. Do you agree? Or would you buy shares of Digital Generation at current prices?
